The storage unit 120 stores a later-described dictionary file in addition to a program for executing OCR (Optical Character Recognition) processing and a program for extracting a character string. The communication unit 130 is means for transmitting and receiving data by connecting to the network 900.

  FIG. 3 is a block diagram illustrating a hardware configuration of the information processing terminal 200. As illustrated in FIG. 3, the information processing terminal 200 includes a control unit 210, a storage unit 220, a communication unit 230, a display unit 240, a UI (User Interface) unit 250, and a photographing unit 260. The control unit 210 is means for controlling the operation of each unit of the information processing terminal 200. Similar to the control unit 210 of the server device 200, the control unit 210 includes an arithmetic processing unit and a memory, and executes various programs.

  The storage unit 220 is a unit that stores data used by the control unit 210. The storage unit 220 is typically a hard disk or a flash memory, but may include a removable medium (detachable storage unit). For example, the information processing terminal 200 that is a mobile phone may include a SIM (Subscriber Identity Module) card or a UIM (User Identity Module) card as part of the storage unit 220. The storage unit 220 stores attribute information representing user attributes. The attribute of the user here is, for example, the user's age (age) or sex. Alternatively, the user's attribute may be the user's hobbies / preferences or occupations.

  The communication unit 230 is means for transmitting and receiving data by connecting to the network 900. The display unit 240 is a means for displaying information such as characters and images. The display unit 240 has a display surface constituted by a liquid crystal display or an organic EL (Electroluminescence) display. The UI unit 250 is a unit that receives input from the user, and includes a keypad (keyboard) and various buttons. The UI unit 250 may be a touch screen (touch panel) provided on the display surface of the display unit 240. The photographing unit 260 is means for photographing a subject and generating image data. The subject in the present embodiment includes an object on which characters are written, such as a signboard, a poster, and a document.

  The schematic configuration of the information processing system 10 is as described above. In the information processing system 10, the information processing terminal 200 can acquire text data of characters included in an image represented by the image data by transmitting image data obtained by shooting to the server device 100. . Here, text data refers to data in which a character string is described by a character code (ASCII, Unicode, Shift_JIS, etc.). The character string here is composed of one or more characters. The server apparatus 100 extracts a character string from the image data transmitted by the information processing terminal 200 and transmits text data to the terminal.

  The server apparatus 100 performs OCR processing and morphological analysis in order to extract a character string from image data. At this time, the server apparatus 100 uses the dictionary file to include a character string (hereinafter referred to as “registered character string”) registered in advance in the dictionary file in the text data, while the extracted character string is the registered character string. If not, the character string is not included in the text data. Further, the server apparatus 100 excludes a specific registered character string from being included in the text data as necessary.

  FIG. 4 is a schematic diagram illustrating the data structure of the dictionary file. The dictionary file of the present embodiment stores registered character strings classified by a plurality of categories. The category can include a category in which a subcategory that is a more detailed classification can be set. For example, subcategories such as “place name”, “person name”, “company name”, and “product name” are set in the category “proprietary noun” illustrated in FIG. 4, and registered character strings corresponding to each subcategory are classified. Has been. The category “sexual expression” is subdivided into “level 1” to “level 3” by subcategories. Here, it is assumed that a registered character string having a higher level of obscurity is classified into a higher level. In the registered character string, the same character string may be classified into a plurality of categories.

  Further, the registered character string may be expressed not by a specific character string but by a pattern match. For example, it is not necessary that all known phone numbers are registered in the category “phone number”, but a character string arranged in accordance with a predetermined rule (in this case, a combination of a predetermined number of characters such as numbers and hyphens). ) Is a registered character string having a data structure that is recognized as a telephone number. As such a registered character string, for example, a character string described by a regular expression can be used. Similarly, for the category of “mail address”, for example, a character string including symbols such as “@” and “.” Together with alphanumeric characters may be recognized as a mail address.

  Note that the dictionary file may be common to each user or may be different for each user. Alternatively, the dictionary file may be different for each user attribute such as a child dictionary file and an adult dictionary file. In such a case, the server apparatus 100 can switch the dictionary file according to the attribute information acquired from the user, and can select a dictionary file suitable for the user.

  FIG. 5 is a functional block diagram illustrating a functional configuration of the server device 100. The control unit 110 of the server device 100 executes the program, thereby causing the image acquisition unit 111, the information acquisition unit 112, the character recognition unit 113, the extraction unit 114, the selection unit 115, the output unit 116, and the editing unit 117 illustrated in FIG. The function corresponding to each part of is realized. The output unit 116 includes a filtering unit 116a and a data processing unit 116b.

  The image acquisition unit 111 has a function of acquiring image data transmitted from the information processing terminal 200 via the communication unit 130. The information acquisition unit 112 is information corresponding to the image data acquired by the image acquisition unit 111, and information for specifying the mode of selection by the selection unit 115 (hereinafter referred to as “selection information”) is the communication unit 130. It has the function to acquire via. The selection information is, for example, attribute information of the user of the information processing terminal 200, but may be input by the user operating the information processing terminal 200. The selection information may be received together with the image data when the image data is received, but may be received independently of the image data. The user selection information can also be transmitted by a person other than the user (for example, an administrator of the information processing system 10 or a guardian when the user is a child).

  The character recognition unit 113 has a function of performing OCR processing on the image data acquired by the image acquisition unit 111 and recognizing characters. In addition, the character at the time of being recognized by the character recognition part 113 has the relationship in which each character was independent, and is not a unit which has a meaning. The extraction unit 114 has a function of extracting a character string by combining a plurality of characters recognized by the character recognition unit 113. The extraction unit 114 appropriately combines adjacent characters by executing morphological analysis and pattern matching with a dictionary file, and extracts a character string (that is, a set of characters based on meaning).

  The selection unit 115 selects one or more categories included in the dictionary file based on the selection information acquired by the information acquisition unit 112. For example, when the user's attribute information is used as the selection information, “sexual expression” is selected if the user is a child of a predetermined age or less. Further, it is preset in the server apparatus 100. In addition, for example, when the user himself selects a category to be excluded from the output target, the selection information may be transmitted in a form in which the category itself is described.

  The output unit 116 has a function of outputting data including a character string extracted by the extraction unit 114 (hereinafter referred to as “output data”). In the present embodiment, the output unit 116 includes character strings as text data, generates output data described in a markup language, and transmits the output data to the information processing terminal 200 via the communication unit 130. Here, the markup language may be HTML (HyperText Markup Language), a subset thereof (Compact HTML), XML (Extensible Markup Language), or the like. Further, the output data is not limited to that described in the markup language.

  The filtering unit 116a has a function of excluding a registered character string classified into the category selected by the selecting unit 115 from an output target from the registered character string extracted by the extracting unit 114 based on the dictionary file. Therefore, the output unit 116 outputs a registered character string classified into a category other than the category selected by the selection unit 115 among the registered character strings extracted by the extraction unit 114. In this way, excluding a registered character string of a specific category from an output target is hereinafter referred to as “filtering”.

  The data processing unit 116b has a function of associating additional information corresponding to the category into which the registered character string is classified, as necessary, with respect to the text data of the registered character string included in the output data. The additional information in the present embodiment is information for specifying a process to be executed when a corresponding registered character string is selected by the user, and is a markup language tag. That is, the data processing unit 116b attaches a tag corresponding to the category of the registered character string to the text data of the registered character string described in the markup language.

  For example, when the output data is described in CHTML, when the category of the registered character string is “phone number”, the data processing unit 116b uses a tag for realizing a so-called phoneto function for the text data of the phone number. Is added. Specifically, when a character string “09012345678” is extracted as a telephone number, the data processing unit 116b adds an anchor tag to the character string and adds “<A href ="tel:09012345678"> 09012345678 </ A> "is converted into text data. In this case, in the information processing terminal 200, the character string “09012345678” can be selected as a link, and when this link is selected, a call can be made to “09012345678”. If the category of the registered character string is “mail address”, the data processing unit 116b adds a tag for realizing a so-called mailto function in the same manner.

  Further, the data processing unit 116b may add a link to a Web site related to the registered character string. For example, the data processing unit 116b allows the company name to function as a link to the top page of the company's website, or the proper noun to the search result page when the search is executed using the proper noun as a search word. It can be made to function as a link. What kind of link the data processing unit 116b adds may be determined for each registered character string or may be determined for each category. Further, the data processing unit 116b may change the processing mode according to the attribute information of the user, such as changing the website (search engine) used for the search according to the age of the user.

  The output unit 116 may or may not include characters recognized by the character recognition unit 113 but not extracted by the extraction unit 114 (for example, characters that are not registered character strings) in the output data. It is preferable that the character string included in the output data is only a registered character string. This is because, in this way, it is possible to prevent a character string not described in the dictionary file from being in a viewable state against the user's intention.

  The editing unit 117 has a function of editing a dictionary file. Here, editing means changing a registered character string or category included in the dictionary file, and includes adding or deleting a registered character string or category. The dictionary file is typically edited by the administrator of the information processing system 10, but may be configured by the user. In particular, if a dictionary file exists for each user, it is desirable that each user can edit their own dictionary file.

  Note that the control unit 110 may realize the functions shown in FIG. 5 by a plurality of programs. For example, the program corresponding to the character recognition unit 113 may be configured as a program different from a program for performing character string extraction or filtering. Alternatively, the server apparatus 100 may be modularized such as a module that executes OCR or a module that performs character string extraction / filtering, and may implement the functions shown in FIG. 5 by exchanging data between the modules. . In such a configuration, each module further includes means for acquiring or supplying data with other modules.

  FIG. 6 is a functional block diagram showing a functional configuration of the information processing terminal 200. The control unit 210 of the information processing terminal 200 implements functions corresponding to the units of the image supply unit 211, the text acquisition unit 212, and the display control unit 213 illustrated in FIG. 6 by executing a program.

  The image supply unit 211 has a function of supplying image data to the information processing terminal 200 (the control unit 110) via the communication unit 230. The image supply unit 211 may prompt the user to shoot using the shooting unit 260 and supply the image data generated by the shooting unit 260, but the image data stored in the storage unit 220 (for example, The image data received by the information processing terminal 200 as an attached file of an e-mail may be supplied. The text acquisition unit 212 has a function of acquiring output data (that is, data including text data corresponding to a registered character string) transmitted from the information processing terminal 200 via the communication unit 230. The display control unit 213 has a function of causing the display unit 240 to display characters and images corresponding to the output data acquired by the text acquisition unit 212.

  FIG. 7 is a sequence chart showing character conversion processing executed in the information processing system 10. The character conversion process shown in FIG. 7 is started when the information processing terminal 200 performs shooting (step S1) and transmits image data to the server device 100 (step S2). The information processing terminal 200 transmits selection information such as attribute information together with (or in advance) image data as necessary.

  When the server apparatus 100 receives the image data, it first executes an OCR process (step S3). When the server apparatus 100 recognizes characters from the image data by executing the OCR process, the server apparatus 100 extracts a registered character string therefrom (step S4). Here, the server apparatus 100 determines whether there is a category to be filtered (step S5). At this time, the server device 100 determines the necessity of filtering by specifying the attribute of the user of the information processing terminal 200 that has transmitted the image data.

  If the server apparatus 100 determines that there is a category to be filtered, the registered character string classified into the category to be filtered is excluded from the registered character string extracted in step S4 (step S6), and the rest. Output data including the registered character string as text data is generated and transmitted to the information processing terminal 200 (step S7). On the other hand, when determining that there is no category to be filtered, the server apparatus 100 omits (skips) the process of step S6 and generates and transmits output data. When the information processing terminal 200 receives the output data transmitted from the server device 100, the information processing terminal 200 displays characters and images according to the output data (step S8). At this time, the registered character string is displayed on the display unit 240 of the information processing terminal 200. This registered character string can function as a link for executing processing such as calling, sending an e-mail, browsing a website, and the like.

Note that image data and output data may be transmitted / received via a Web browser, or may be transmitted / received as an attached file of an e-mail. Alternatively, the information processing terminal 200 may be able to execute such character conversion processing by executing an application that manages from image capturing to display of output data.

  As described above, according to the present embodiment, it is possible to perform extraction and filtering of registered character strings using a dictionary file. That is, according to the present embodiment, it is not necessary to separately prepare a registration character string extraction dictionary and a filtering dictionary (black list or white list). This reduces the trouble of adding or deleting a character string to be excluded from the output target and, for example, a problem of output caused by forgetting to register such a character string in one dictionary but in the other dictionary. It is also possible to prevent.

  In addition, according to the dictionary file of the present embodiment, it is possible to change a character string that is desired to be excluded from an output target simply by changing the category to be selected. Therefore, it is easy to change the character string. For example, according to the dictionary file of the present embodiment, even if a plurality of users use the same dictionary file in common, the character string excluded from the output target is changed for each user only by changing the category to be selected for each user. It is possible to change. For example, according to the dictionary file illustrated in FIG. 4, it is possible to easily present a registered trademark to one user and not present a registered trademark to another user. Further, according to the dictionary file illustrated in FIG. 4, the filtering of terms depending on the subjectivity of individuals such as expressions that may make others uncomfortable can be performed for each category, and further for each subcategory (for each level). ) Can be selected.

  Furthermore, according to the configuration of the present embodiment, the dictionary file is stored in the server device 100, and the server device 100 performs character string extraction and filtering. Therefore, it is not necessary to edit the dictionary file for each user. In this way, it is possible to more easily and reliably cope with a new word (new word) as compared with a case where each user individually edits a dictionary file.

[Modification]
The present invention is not limited to the embodiment described above, and can be implemented in various forms. The present invention can be implemented according to the following modifications, for example. Note that these modified examples may be implemented in combination as appropriate.

(Modification 1)
The filtering of the present invention may be executed not on the server device side but on the information processing terminal side. For example, the present invention can also be implemented in an aspect in which an OCR process is executed on the server device side, a character recognized by the OCR process is acquired by an information processing terminal, and character string extraction or filtering is executed. Further, according to the present invention, a dictionary file and a necessary program are provided in the information processing terminal, so that the information processing terminal can be executed alone without using the server device.

  FIG. 8 is a functional block diagram showing a functional configuration of the character conversion apparatus according to the present invention. The character conversion device 310 illustrated in FIG. 3 is acquired by the character string acquisition unit 311 using the character string acquisition unit 311 that acquires a character string that has been subjected to OCR processing or morphological analysis as an input character string, and the dictionary file 320. An extraction unit 312 that extracts a registered character string from the input character string, a selection unit 313 that selects a category to be excluded from an output target, and a category other than the category selected by the selection unit 313, and the extraction unit 312 And an output unit 314 that outputs the registered character string extracted by the above. Note that the dictionary file 320 may be external to the character conversion device 310, but may be stored in a storage unit included in the character conversion device 310.

  By providing the character conversion device 310 shown in FIG. 8, the information processing terminal can extract and filter a registered character string with respect to an input character string transmitted from the server device. Alternatively, the information processing terminal has a function of recognizing a character string from an image in addition to a function corresponding to the character conversion device 310, thereby performing processing for selectively outputting a necessary registered character string based on image data. It can also be realized by a processing terminal alone.

  Note that the character string acquired by the character string acquisition unit 311, that is, the input character string does not need to be a character string obtained by OCR processing. For example, the input character string may be a character string input by the user. In this case, the character conversion device 310 can be applied to character conversion such as kana-kanji conversion. In this case, if the input character string and the registered character string have a semantic correspondence, such as the input character string is hiragana and the registered character string is kanji (or mixed kanji). The character codes do not have to match.

(Modification 2)
In the embodiment described above, the control unit 110 operates so that the extraction unit 114 extracts the registered character strings of all categories and then excludes the registered character strings of some categories by the filtering unit 116a. In such an operation, even registered character strings of categories that do not need to be extracted are once extracted. Therefore, the control unit 110 may extract only the registered character strings classified into categories other than the category selected by the selection unit 115 in the extraction unit 114 instead of the registered character strings of all categories.

  That is, the present invention may be configured to exclude registered character strings of categories that should be excluded after extracting all registered character strings corresponding to the input character string, and among the registered character strings corresponding to the input character string, Only registered character strings of categories other than the categories to be excluded may be selectively extracted.

(Modification 3)
The registered character string of the present invention may include those classified into two or more categories such as “product name” and “registered trademark” in the example of FIG. 4. Such a registered character string may not be output only when all the categories into which the registered character string is classified are selected, but at least one of the categories into which the registered character string is classified If is selected, it may not be output.

(Modification 4)
The present invention may be configured such that a plurality of dictionary files are associated with the same user, and the user switches the dictionary file used by his / her own operation. Or this invention can also be comprised so that the dictionary file to be used may switch according to a time slot | zone. In this way, the dictionary file to be used can be made different between working hours and other times. Further, the present invention provides a dictionary file used in accordance with position information indicating the position of the information processing terminal (that is, the position of the user) when the information processing terminal has a positioning function based on GPS (Global Positioning System) or the like. May be switched.

  The same applies not only to the dictionary file itself but also to the category of the dictionary file. That is, according to the present invention, the selected category (category excluded from the output target) may change according to the time zone or the user's position.

(Modification 5)
The present invention excludes a registered character string classified into a category other than the category selected by the selection unit from the output target instead of excluding the registered character string classified into the category selected by the selection unit from the output target. You may do. In such a case, the character conversion device according to the present invention includes a character string acquisition unit that acquires an input character string, and a dictionary file that stores a plurality of registered character strings classified by a plurality of categories, and stores the character string acquisition unit. An extraction unit that extracts a registered character string corresponding to the input character string acquired by the above, a selection unit that selects one or a plurality of the categories, a category selected by the selection unit, and the extraction unit And an output unit that outputs the registered character string extracted by (1).

(Modification 6)
The present invention can be specified not only as a character conversion device but also as a server device (or information processing terminal) including a character conversion device or a character conversion system including the server device. The present invention can also be specified as a character conversion method for outputting a registered character string corresponding to an input character string, or as a program for causing a computer to function as a character conversion device. Such a program may be provided in a form recorded on a recording medium such as an optical disk, or may be provided in a form such that the program is downloaded to a computer via a network such as the Internet, and the program can be installed and used. Is possible.
